Chikungunya Virus

Chikungunya Fever is a viral disease which, like dengue fever is transmitted by mosquitoes. The disease was first recorded in 1952 and has affected millions of people in Africa and Asia. The
word Chikungunya means 'that which bends up' in Kimakonde, a language spoken by an African tribe from the eastern border between Mozambique and Tanzania.

Chikungunya is transmitted by the Aedes aegypti mosquito as well as the Aedes a/bopictus mosquito. These mosquitoes bite mostly during the day, with peak activity two hours after sunrise and two hour~ before sunset.

For protection during outbreaks of chikungunya, clothing which minimizes skin exposure to the day-biting vectors is advised. Repellents can be applied to exposed skin or to clothing in strict accordance with product label instructions. Repellents should contain DEET, Picaridin, oil of lemon, eucalyptus or IR3535. For those who sleep during the daytime, particularly young children, or sick or older people, insecticide treated mosquito nets afford good protection. Mosquito coils or other insecticide vaporizers may also reduce indoor biting.

Basic precautions should be taken by people traveling to risk areas and these include use of repellents, wearing long sleeves and pants and ensuring rooms are fitted with screens to prevent mosquitoes from entering.
